Childhood and Education
Peter Halsey Cook was born in New Jersey, according to his IMDb biography. However, his connection with the Hamptons goes back to childhood. In a 2015 interview with Dan’s Papers, he recalled spending time around Bridgehampton, where his grandparents lived. He also spoke about enjoying cartooning as a boy.
In the same interview, Cook explained that he enjoyed both creative work and subjects such as mathematics and science. Architecture offered a way to bring those interests together. He studied at Rensselaer Polytechnic Institute in Troy, New York, and said he graduated with a degree in building sciences. The subject combines an understanding of buildings with the practical knowledge needed to make designs work beyond the drawing board.
From Modelling to Architecture
Cook also worked as a model during his younger years. A Cityfile profile, preserved in the Gawker archive, describes his modelling work while he was in college. It also refers to an appearance on a GQ cover in 1981. This part of his history can surprise readers who know him only as an architect. However, modelling was an earlier chapter, while designing homes became the main focus of his professional life.
The move into architecture involved years of practical training. In his own account, Peter Halsey Cook described a five-year internship with Bridgehampton architect Eugene L. Futterman. He then opened his practice in 1987. That timeline places the start of his business almost a decade before his wedding to Brinkley, when he was already working within the Hamptons design community.
Building a Practice in the Hamptons
Peter Halsey Cook established a practice known as Peter Cook AIA, Architect. Its work has focused on custom homes, meaning homes planned around a particular client and building site. Architectural reporting has connected his practice with the Hamptons communities of Southampton and Water Mill. A separate professional biography for architect Douglas Moyer also records Moyer’s earlier work at Cook’s Southampton office, offering another record of the firm’s place in the local design community.
The Cityfile profile describes Cook’s work on large homes with shingle exteriors, roof windows and fireplaces. Shingles are small overlapping pieces used to cover outside walls or roofs. This style has a strong connection with coastal houses in the area. The profile also names Anne Hearst and writer Jay McInerney among his clients. These details help explain the kind of residential work associated with his name, beyond the entertainment stories about his marriage.
His Approach to Home Design
In a 2016 interview with Dan’s Papers, Cook explained that he starts with the homeowner’s needs and the qualities of the site. He said he did not see himself as an architect who applies one fixed style to every house. Instead, the location and the way a client wants to live help shape the plan. This approach can affect the placement of rooms, the use of outdoor space and the overall feel of a home.
He also discussed parts of architecture that visitors may never notice. Heating, lighting, media equipment and other systems need careful planning so they fit smoothly into a building. Cook noted that custom design takes time, especially when a sensitive site brings extra building rules and permits. His comments offer a useful view of the job: an attractive house depends on planning, technical work and clear discussions with its owners, as well as its appearance.
Meeting and Marrying Christie Brinkley
Peter Halsey Cook and Christie Brinkley first met in 1979, according to People’s account of her relationships. They later reconnected through a mutual friend in 1995. By then, Brinkley was already a well-known model with several previous marriages. Cook’s career was based in architecture. Their relationship brought those two working worlds together and made his name familiar to readers who had never followed the Hamptons property market or local design scene.
The couple married on September 21, 1996, at Brinkley’s Bridgehampton property. He became her fourth husband, following Jean-François Allaux, Billy Joel and Richard Taubman. The marriage lasted legally until 2008, although they separated in 2006. Keeping those two dates separate helps avoid a common source of confusion. They spent about ten years together as a married couple before separating, while the divorce process took longer to bring the legal marriage to an end.
Sailor and Jack Brinkley-Cook
Peter Halsey Cook and Brinkley welcomed their daughter, Sailor Lee Brinkley-Cook, on July 2, 1998. Sailor later built a public career in modelling. Her work has made her name familiar to a younger audience, sometimes leading readers back to questions about her parents. She is Cook and Brinkley’s biological child together. Her connection with both parents is regularly mentioned in profiles of her career and in coverage of Brinkley’s children.
Cook also adopted Jack Paris, Brinkley’s son from her marriage to Richard Taubman. Jack became known as Jack Paris Brinkley-Cook. This distinction is useful when reading accounts that describe the former couple as having two children: one is their daughter, and the other is Cook’s adopted son. Brinkley also has an older daughter, Alexa Ray Joel, whose father is Billy Joel. Alexa is Cook’s former stepdaughter.
The Separation in 2006
The marriage between Peter Halsey Cook and Brinkley broke down after his affair with Diana Bianchi became public. Bianchi was an 18-year-old employee, and Cook later acknowledged the affair in a television interview. The couple announced their separation in 2006. The story quickly became a major part of the coverage around them, drawing attention away from his architectural work and towards the end of their marriage.
Brinkley returned to the experience in her 2025 memoir, Uptown Girl. As reported by People, she recalled learning about the affair when a man approached her at a school graduation in the Hamptons. Her book describes her own experience of that moment and the difficult period that followed. It is important to identify these memories as her account. The separation itself, the affair and the later divorce were also covered by reporting at the time.
The Divorce Settlement and Later Disputes
The divorce case reached a settlement in July 2008 after a widely reported trial. An Associated Press report published by The Independent said Brinkley would pay Cook $2.1 million and keep 18 disputed Hamptons properties. She received custody of Sailor and Jack, while Cook received parenting time. These were the main terms made public. The report also stated that other parts of the agreement were confidential, so the published figures did not describe every detail.
The end of the divorce did not immediately end their disagreements. Further disputes about parenting and money kept the former couple in the news. CBS New York reported another settlement in June 2012. This longer timeline explains why some accounts mention a court battle lasting several years after the separation. The dates refer to different stages: the relationship ended in 2006, the divorce followed in 2008, and further disagreements continued afterwards.
Later Marriages and the Capri Wedding
After the divorce, Peter Halsey Cook married Suzanne Shaw. She was publicly identified as his wife in 2012 reporting, but that marriage also ended. By November 2014, Entertainment Tonight was reporting on Shaw as his former wife. It also covered her public apology to Brinkley over comments made during the earlier disputes. These reports place the relationship within the wider timeline without needing to rely on claims about private conversations or everyday married life.
Cook later became engaged to Alba Jancou in Santorini, Greece, in September 2019. They married in Capri, Italy, in September 2023. In an interview with People, the couple discussed their small ceremony at Hotel Luna, overlooking the Faraglioni rock formations. Six guests attended. They also explained that earlier wedding plans had been delayed by the pandemic. The published interview provides a clear record of that wedding and the couple’s reasons for choosing the location.
His Work and Public Life in Recent Years
Later property coverage shows that Cook’s architectural work continued beyond the divorce years. A November 2025 feature on Hamptons.com credited him with a waterfront home completed in 2024 in Sag Harbor. The property was described as having open living spaces, broad water views, private terraces and several leisure areas. This is a more recent example of the large custom homes connected with his career, rather than an assumption based only on profiles published many years earlier.
Public interest in his past marriage also continued when Brinkley released her memoir in 2025. These two kinds of coverage serve different purposes. Property features describe buildings, while memoir reporting presents personal memories and experiences. Neither gives a complete picture of his finances or daily life. In particular, the $2.1 million divorce payment should not be treated as his current net worth. A payment reported in 2008 cannot establish the value of his assets and debts today.
Conclusion
Peter Halsey Cook is an architect whose public history includes a long connection with the Hamptons, a residential design practice and a widely reported marriage to Christie Brinkley. Their daughter Sailor, his adoption of Jack and the divorce remain central parts of his biography. His later marriages and more recent property work add further chapters. Understanding the dates and keeping professional records separate from personal accounts gives readers a clearer view of his life and career.
